phpWebLogAnalyzer TODO list
---------------------------

- possible bug: SQL clausule substring() called on non-string types
- possible bug: calling getSessionCount() without registerAccess()
- create utility for converting data from weblog_core_accesses table to 
  weblog_accesses table
* add support for weblog_core_accesses table; creating entry for weblog_accesses
  is very difficult for CPU and SQL server
  - table is called weblog_accesses_raw
- source formating PEAR compliancy
* class style PEAR compliancy
- PEAR compliant error handling
- ident stuff: move index column and table name from *_username to *_user
- think about possible table joins:
	weblog_ident_usernames w/ weblog_remote_idents
	weblog_http_hosts w/ weblog_remote_hosts (what if HTTP_HOST is IP address?)
* session column
- Perl API functions for register hits
- web interface (frontend) for analyzing and manipulating with statistics

- why this doesn't work?
